If that doesn't work you can use Networked Blogs http://www.networkedblogs.com/ or RSS Grafitti http://www.facebook.com/RSS.Graffiti for posting to Facebook walls if you prefer. RSS Graffiti periodically checks the RSS/Atom feeds that you specify and posts any new entries it finds to the Facebook Walls that you specify. You can get any feed written on any wall (Facebook Profiles, Fan Pages, Groups, Events and Application Profile Pages). In fact, multiple feeds to multiple walls. You choose the combination.

I'm having the same problem, except my facebook publicize will work fine for a week or so and then drop without me having done anything to mess it up.
If I switch to the RSS Graffiti, how much of my post will show on my facebook page?
